http://answers.opencv.org/question/66681/difference-between-blur-and-dilate/?comment=66693#post-id-66693Actually i am using blur operation to smoothen the image. Strangly gpu::blur is taking more time than c::blur hence i was planning to replace it with dilate. But couldnt exactly figure out their effect on same image.Mon, 20 Jul 2015 11:39:06 -0500http://answers.opencv.org/question/66681/difference-between-blur-and-dilate/?comment=66693#post-id-66693Comment by sturkmen for <p>can anyone please explain the difference between blur and dilate ? mathematical as well as layman explanation would be really nice </p>

http://answers.opencv.org/question/66681/difference-between-blur-and-dilate/?comment=66695#post-id-66695i can't test gpu::blur but it must be faster than cv:blur Afaik. try [gpu::GaussianBlur](http://docs.opencv.org/modules/gpu/doc/image_filtering.html#gpu-gaussianblur) or [gpu::sepFilter2D](http://docs.opencv.org/modules/gpu/doc/image_filtering.html#gpu-sepfilter2d)Mon, 20 Jul 2015 11:52:22 -0500http://answers.opencv.org/question/66681/difference-between-blur-and-dilate/?comment=66695#post-id-66695Comment by Prem for <p>can anyone please explain the difference between blur and dilate ? mathematical as well as layman explanation would be really nice </p>
http://answers.opencv.org/question/66681/difference-between-blur-and-dilate/?comment=66691#post-id-66691@sturkmen yes. Can you please explain what do they do to an image differently?
